How

If you used a site builder like Squarespace or Weebly they have help docs on how to set it up if it isn’t already.

Otherwise how you enable it depends on your webhost. Some hosts (e.g. A2 Hosting) offer free continuous Let’s Encrypt security. Others, like Bluehost, make you jump through some additional hoops but may have a free option as well.

Failing a free easy option you’ll have to pay a subscription for a Secure Sockets Layer (SSL) certificate. Just a cost of living on the internet, 2018-style.

As always, if you have questions talk to your website collaborator!

Notes

Free SSL (e.g. Let’s Encrypt) should NOT be used for sensitive data entry such as credit card info, social security numbers, etc. For that a warrantied service should be used instead. Ask your webhost or web developer.

There are some complexities around third-party services such as Google Search Console and Bing Webmaster Tools, so consult with your website pro about that.

If you are ever wondering “should I enter my [password, credit card information, or other sensitive information]?” on a site you’re visiting, do NOT simply trust it because you see https:// in the address bar. That’s a good sign, but when in doubt be safe.
